LINE-PEN.

SPECIFICATION forming part of Letters Patent No. 623,391, dated April 18, 1899.

Application filed May 21, 1898- Serial No. 6 81,362. (No model.)

To (tZZ whom, it may concern.-

Be it known that I, LYMAN H. ZEIGLER, of Millbank, in the county of Grant and State of South Dakota, have invented a new and Improved Line-Pen, of which the following is a full, clear, and exact description.

This invention is a line-pen constructed in such a manner as to facilitate the rapid adjustment of the pen, thus enabling lines of varying width to be conveniently and effectively drawn.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the invention. Fig. 2 is a side elevation thereof. Fig. is a fragmentary view showing the wheel of the adjusting-cam. Fig. 4 is a top view of the adjusting-cam and the coacting parts. Fig. 5 isa detail section on the line V V of Fig. l, and Fig. 6 is a detail section on the line VI VI of Fig. 1.

The pen is provided with two arms 7 and 7, each in turn being provided with a lug 8, the said lugs being pivotally joined to each other by means of a rivet 9. The arms 7 and 7 have each a finger, which fingers are designated, respectively, 10. and 11. The fingers l0 and 11 meet at their outer ends to form the point of the pen, as is common in linepens. Attached rigidlytothe upperportion of the finger is a thin plate 12 of gold or other durable non-corrosive material. This plate extends between the fingers 10 and 11 and has its free end twisted to form an ink-spreading portion 14, as shown best in Figs. 1 and 6.

The arm 7 is inclosed in a tube 15. The tube 15 has the material forming the same extended outward from said tube to form a flange 17, which is provided with a series of perforations 18, in any one of which may be fitted the curved end 19 of the spring 20. The opposite end 21 of the spring is bent to form a hook which engages with the arm 7. This spring serves to keep the arms separated from each other and to throw the fingers 10 and 11 into engagement with each other. A finger-plate 16 is provided that is formed of a continuation of the material forming the flange 17, such finger-plate having diagonal edges and being extended toward the arm 7, so that the finger-plate 16 may rest against the middle finger of the person using the pen.

The outer portion of the tube 15 is 0011- tracted to form a plate 22, which is slit into two parts 22, as shown in Figs. 1 and 4. Mounted to turn in the plate 22 is a spindle 23, one end of which is provided with a milled finger-wheel 24, fixed to the spindle and lying against the outer side of the plate 22. Fixed'to the spindle 23 and lying against the inner face of the plate 22 is a cam 25. The other end of the spindle 23 is provided with a milled nut 26, pressed by a helical spring 27, fastened to the spindle. The free end of the arm 7'" is provided with a rib 28, which is adapted to bear against'the spindle 23. The spindle 23 is provided with two or more notches 29, which coact with the rib 28, so as to permit the person using the pen to determine the relative position of the two arms 7 and 7 by the click of the rib 28 over the walls of the recesses 29.

In using the pen it is grasped with the forefinger bearing againstthe tube 15, with the finger-plate 16 resting against the middle finger, and with the ball of the thumb bearing on the arm 7. Bythese means the person using the pen may operate it with ease, and by pressing the arm 7 toward the arm 7 the fingers 10 and 11 will be separated from each other. The cam has its cammed face in position to be engaged by the free end of the arm'7. This cam is adjusted through the medium of the milled wheel 24, the face of which is provided with numbers, as shown in Fig. 3, so that the positions of the wheel and cam may be determined and recorded. According to the position of the cam 25 the movement of the arm 7 toward the arm 7 is controlled. If the cam be arranged so that the arm strikes the high portion of the cammed face the line drawn by the pen will be slight;

able on the spindle 23, so as to regulate the outward movement of the arms 7 and 7, while the spring 27 holds the nut from turning idly on the spindle. When the cam is adjusted so that the arm '7 has the greatest possible movement, the rib 28 of the arm '7 will move along the notches 29 of the spindle 23, because the notches are arranged to be thrown into this position when the cam is thrown to permit wide movement of the arm 7. The operator moving the arm 7 so that the rib 28 sounds in passing over the notches 29 can thus determine the position of the pen by the sense of touch and can operate it more effectively. By changing the position of the spring 20, so that the end 19 may be changed from one of the openings-18 to the other, the tension which the spring exerts against the arm 7 may be regulated. hen the pen is so adjusted that the rib 28 engages the notches 29, it is desirable that the spring 20 exert all possible pressure on the arm 7, so that there will be nolikelihood of the rib 28 becoming seated in one of the notches and thus impairing the effective operation of the device.

Having thus described my invention, I claim as new and desire to secure by Letters Paientl. A line-pen having two pivotally-connected arms, a spring-bearing between the arms and pressing them apart, two fingers rewith each other to form the pen proper, the

said spring serving to keep the fingers together and a thin metallic plate fastened to one finger and extended between the two fingers.

2. A line-pen having two fingers loosely connected at one end and coacting with each other to form the pen proper, and a thin metallic plate held between the fingers and having its free portion twisted to spread the ink.

3. The combination of two arms mounted to swing toward and from each other, a spindle carried by one of the arms, a cam carried by the spindle and serving to limit the movement of the arms toward each other, and a springpressed nut carried at the opposite portion of the spindle.

4. A line-pen having two fingers coacting with each other to form the pen proper, and a thin plate held between the fingers and serving to dispose the ink between the fingers, substantially as described.

5. The combination in a pen of two pivotally-connected arms carrying fingers forming the pen proper, and a spindle connected with one of the arms and having notches therein, with which notches the other arm coacts so as to removably hold the arms at any desired adjustment, substantially as described.
